I see not what is wrong, but here is a running sample:
namespace AutomapperTest2
{
internal class Program
{
#region Methods
private static void Main(string[] args)
{
// Configure the mappings
Mapper.Initialize(cfg =>
{
cfg.CreateMap<ApplicantEducation, ApplicantEducationVM>();
cfg.CreateMap<Applicant, ApplicantVM>().ReverseMap()
.ForMember(x => x.Education, x => x.Ignore());
});
var config = new MapperConfiguration(cfg => cfg.CreateMissingTypeMaps = true);
var mapper = config.CreateMapper();
Applicant ap = new Applicant
{
Name = "its me",
Education =
new ApplicantEducation
{
SomeInt = 10,
SomeString = "sampleString"
}
};
// Map
ApplicantVM apVm = Mapper.Map<Applicant, ApplicantVM>(ap);
Applicant apBack = Mapper.Map<ApplicantVM, Applicant>(apVm);
}
#endregion
}
/// Your source classes
public class Applicant
{
public ApplicantEducation Education { get; set; }
public string Name { get; set; }
}
public class ApplicantEducation
{
public int SomeInt { get; set; }
public string SomeString { get; set; }
}
// Your VM classes
public class ApplicantVM
{
public string Description { get; set; }
public ApplicantEducationVM Education { get; set; }
public string Name { get; set; }
}
public class ApplicantEducationVM
{
public int SomeInt { get; set; }
public string SomeString { get; set; }
}
}
}
